Specification of Letters Patent.

Application inea october er, isis. sei-iai No. 797,457.

To all whom it may concern.' i n lle it known that l, JOHN N. HAHN,citiw Zen of the United States, residingat Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in Packing-Trays for Fragile Articles, of which thefollowing is a 'lhis invention relates to an improvement in packingtrays for fragile articles, such as lamp shades and other articleshaving denieshaped or bowl-like bodies, all substantially as shown anddescribed and particularly pointed out in the claiin.

lfn the accompanying drawings, Figure l is a bottoni vieu7 of a trayconstructed according to the present invention, and Fig. E2 is a crosssection thereof on line 2Q, Fig. 1. Fig. 3 is a sectional elevation of aportion of an inclosed casing and of a pair of trays and shades thereinand representing an int` provenient on the construction shown in Lettersliatent of the United States issued to ine April 2Q, 1918, and numbered1,059,359.

`ln the saidpatent l show a tray made of double-faced corrugated paperas in the present application, and the said tray or trays -were and areprovided with Wings 4l and respectively, as in the present case andserving as the immediate supports for the trays neat Within the Wall ofthe ci se c and overlapping one Within the other as seen at the left inliig. 3. rll`he presentinvention `conuorises,what l regard as a verymaterial and valuable improvement upon the tray shown in said patent,and consi sts in a series of specially constructed sp urs or tongues 2as the iinniediate supports of the shades, in combination with the sideWings or supports 4; and 5 as the supports forl the trays theinselveswith their load, the Whole constituting a new and original article ofmanufacture.

ils formerly inade the tray has been found deticient or defective inthat portion which held or engaged the shade because it had nothingincre than a round hole With a prac tically harsh narrow edge in or onwhich the shade was seated at about its middle or swell portion and withthe larger or Wider portion thereof extending above said seat. lhis wasfound to serve the purpose in a sense, as where the handling of thepackage Was very careful, but such handling is eX- ceptional and it wasfound that a mere edge support really jeopardized every shipmentandinthe end entailed great loss breakage of shades. Of course the Wingsofthe tray actually sustain the burden. and these are a necessary partof the `present invention, but close and safe packing of the shaderequires that it be relieved of the sharp edge formerly used and given aspring which not only eliminates suoli edge but supports the shade Whereit cannot be injured by a side thrust on the package. Formerly there Wasconstant danger of the shade being cracked or broken becauseporcelainshades are very fragile and side thrust or pressure on thepackagewas liable to deliver a cracking or breaking blovvwthrough saidseat, particularly since the board is rigid and in a thrust is about asdangerous as an all Wood board would be Vin the saine re lation. Thepresent invention is therefore especially directed to this defect in theformer construction, and remedy is afforded by oinitgrip i ting the saidedge as an edge and substitut#` ing the Vshaped spurs or tongues 2 asthe immediate supports for the shades. lt is especially to be noted thatall the said spurs start from or` in a circular crease 3 in the bottomof the tray and run to a point at the` center and that the stock which,in the old construction, was cut out toform the hole forthe shade, isutilized in this tray as the immediate support for the shade. l ineanthat the shade is .suspended or supported upon the hat and cushioningsides of the said spurs or` tongues `which engage the bulge of the shadea considerable distance beneath the body or horizontal. portion of thetray Where the sharp edge formerly engaged the shade, and that the saidspurs in effect and fact are a series of practically rigid springs,constituting together a spring basket for the shade. l say rigid becausethe board I use is a rigid board necessarily. The

internal corrugated sheet and the outer layers of strong paper pastedthereon inake a rigid structure, and the bending of 'the spurs ortongues on the curveof the crease 3 `would be physically impossible asthe saine bent herein. if the said crease did not outline and aiford thebend required. Furthermore, with the said crease as I make it I provideeach spur with a spring hinge in which the real secret of this inventionresides. It will be seen that the crease is of such depth as to any ofthe sheets. It follows that a hinge is made with three layers of paperworking together and strengthening each other. Furthermore, the saidcrease is onlyof such width that when the spurs or tongues are turneddown to a supporting inclination for the shade the side walls orshoulders u: and y come together and serve as stops to furtherdepression or swing of the spurs. This is their supporting position andit would require actual violence to press a spur farther back andrequire the breaking of its support.

Of course I do not weight a set of spurs in a given tray with more thana single shade, and utilize the wings 4i and' 5 as before to sustain theload, but they will carry a much heavier weight than an ordinary shadeand maintain their spring quality for almost an indefinite period, thusadapting the tray to repeated use. This construction also re moves theshade from the body of the tray by the distance shown in the interveningspace 7, and hence it does not impinge upon the said body at all. On thecontrary, the shade is bodily removed from the body of the tray such aconsiderable distance that no side thrust upon the package can possiblyreach the shade, unless it is of a package crushing character. Thisalone insures the safety of the shade in handling and shipping, but thisis not all.

It will be seen that the spurs are struck i from a curved crease ordepression and not from a straight one. This produces lines ofresistance which cross each other when the spurs are bent down andprovides a permanent spring effect which would not be possible if thesaid crease and hinges were straight. It follows that the total effectof this construction at the base of the spurs is such as produce apractical stoppage and resistance to the spurs against furtherdepression than shown and which cannot be extended farther downwardwithout breaking down the shoulders m and y or rupturing the hinge e,and that the tendency in the spurs to spring back is permanent. It willCopies of this patent may be obtained for ve cents each, by addressingthe Commissioner of Patents,

also be noticed that the circle of the crease 3 for the spurs is cast onlines at least as large as the cross section of the shade at its largestportion and it might be larger relatively7 because I want to provideplenty of room in the space 7. As it is the shade would drop through thetray if it were not adequately supported by the spurs as shown. But byspringing the spurs from theirbase edge in said crease and abutting theshoulders@ and g/ in the angle and depending on the three-ply hingeformed by the crease 3 and its segmental curvature for the desiredresistance the total sustaining value of the six spurs is found to besuch as would hold up a materially heavier object than a porcelain orlike shade. It will be noticed also that the eX- tremities of the spursflex somewhat to accommodate themselves to the neck of the shade, sothat the entire length of the spurs is practically utilized and a springbasket carrier or crib is formed for the shade in which the shade doesnot come in contact with the body of the board at any point but isremoved therefrom all around by the space 7.

That I claim is:

A packing tray to carry fragile articles made from three ply corrugatedpaper board and having a series of tapered spurs radially disposed abouta common center, the said spurs having each a spring hinge at its baseformed from the said plies of paper pressed together at one side in acrease and opposite shoulders at the sides of said crease limiting thedownward turn of the spurs, whereby when the spurs are inclined on theirhinges to carrying position the said shoulders will contact and resistfurther depres`r sion.

In testimony whereof I aHiX my signature in presence of two witnesses.
